WATCH-REGULATOR.

SPECIFICATION forming part of Letters Patent; No. 369,005, dated August30, 1887.

Application iiled July 2l, 1886.

.To @ZZ whom, it may concern:

Be it known that I, JOSEPHV. IIURD, a citizen of the United States,residing at Aurora, in the county of Kane and State of Illinois,

5 have invented new and useful Improvements in Vatch-Regulators, ofwhich the following is a specification.

My invention relates to improvements in watch-regulators; and itconsists of the perc culiar combination and novel construction andarrangement of the various parts for service, substantially ashereinafter fully set forth, and specically pointed out in the claims. yThe object of my invention is toprovide an improved watch-regulatorwhich can be easily and readily applied to watches of any class andwhich shall possess superior advantages in points of simplicity anddurability of construction and ease of application and adjustment.

In the accompanying drawings, which illustrate a watch regulatorembodying my invention, Fig. lis atop plan view, on an enlarged scale,of so much of a watch-movement as is necessary-for a properunderstanding of my invention; and Fig. 2 is a vertical sectional vie'won the line x x of Fig. 1.

Referring to the drawings, in Which like letters of reference denotecorresponding` parts 3o in both iigurcs, A designates the regulator, andB the plate of the watch-movement, which are of any preferred pattern,my improvements being applicable to any style of Watches.

O designates my improvement, Which consists, essentially, of abase-plate, D, an index, E, having a scale or the usual subdivisionsthereon, a pinion or gear-wheel, F, and a slide, G, to be actuated bythe pinion and carrying the free end of the regulator to adjust thelatter for the purpose oi' varying the tension of the hair-spring andregulating the rapidity of the strokes of the balance-wheel. The indexis made curved or segmental in form, and at its ends it has transverseholes or openings formed therein, through which are passed screws c', tosecure it to the base-plate. The base-plate is also curved or madesegmental in form to correspond with the index, which bears or reststhereon, and the ends of the base- 5o plate are also provided withtransverse openings or apertures. When the index is fitted or Serial No.208,644. (No model.)

adjusted on the baseplate, the openings therein align with the openingsin the baseplate, and through these aligned openings are passed thescrews c', to secure both the base- 55 plate and index to the plate B ofthe watchmovemcnt. One of the vertical faces at the sides of the indexis inclined inwardly and downwardly, as clearly shown in the sectionalview, and against this inclined face of the in- 6o dex bears a similarface of the slide G, which is curved longitudinally or made segmental inform to bear closely against the segmental index, which serves to guideand prevent displacement of the slide during its movements.

The slide is made approximately V shape in cross-section to form the twoinclined faces, with the apex thereof uppermost and the hase resting onthe base-plate D, over which it moves freely. One of the side faces isleft 7o smooth and bears against the index, and the opposite side faceis provided with a series of very fine teeth, with which meshcorresponding teeth on the periphery of a gear-wheel or pinion, F. Thesides of this gear-wheel are beveled or inclined to correspond to theinclination of the toothed face of the slide which the gear-wheelactuates, and the said wheel is journaled on a screw or rivet, f, whichis secured on the base-plate D, the said plate be- 8o ing provided witha laterally-extended lug, d', for the support of the gear-wheel and itsshaft. rlhe gear-wheel has transverse incisions or cuts f in its upperexposed face, into which the end of a screw-driver or other implementcan be readily inserted to turn or rotate the gear-wheel in eitherdirect-ion, and thus move the slide back or forth, and thesaid slide hasa recess or groove formed in the upper edge thereof, in which is fittedone end ofthe swinggo ing regulator, so that when the slide is moved thefree end of the regulator is carried with it. The teeth on the slide andgear-wheel are made very ne, for securing a minute adjustment of theregulator, as is cssentialinwatches of Very fine make.

The operation of my invention will be readily understood. The gear-wheelis turned in the proper direction by inserting a screw-driver or othersuitable implement in the grooves of ico the same, and the slide is thusactuated in the properdirection, and carries with it the free end ol theregulator to vary the tension of the hair-spring and the strokes of thebalanee- Wheel.

In applying the device to a watch-move ment the gear-wheel is rsta'tiixed to the baseplate, and the index and slide are then properlyadjusted on the said plate with relation thereto and the gear-wheel, sothat the openings in the index register with the openings in thebase-plate and the teeth on the rack mesh with the teeth of the pinion,after which the screws e are passed through the aligned openings in theindex and base-plate to secure them to the plate B ol' thewatch-movement, the free end of the regulator being ittedin the recessof the slide.

It will be obvious that if any of the parts or elements of thisimprovedregulator become broken or out of order they may be removedandreplacedatpleasure. rlheregulatorproper, A, being merely set in aslot in the slide, need not necessarily be removed when the slide istaken out, but may be operated by hand in the ordinary manner.

My improvements are simple and durable in construction, easily appliedto a watch, readily adj usted,and effective for the purposes designed.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- l. In aregulator for Watches,the gear-wheel F, in combination with the slide G, actuatedby thegear-wheel, a regulator detachabl y connected to the slide, and astationary index, separate from the slide, over which the regulatorsweeps in its movements, as set forth.

2. In a regulator' for watches, the gear-wheel F, in combination withthe base-plate D, the

endwise-moving slide G, V-shaped in cross 4o section, seated in guidesor ways on the base, said slide being actuated by the gear-wheel, andthe regulator A, detaehably connected to the slide, as set forth.

3. The combination ol1 a base-plate, a gearwheel carried by the saidplate, an index al'- fixed to the plate, and a slide bearing on theplate and against the .index and having teeth meshing with thegear-wheel, one end of the regulator being connected with the slide,substantially as described.

el. The combination of an index having an inclined face, a slide,substantially V shape in cross-section, and having a smooth face bearingagainst the inclined face of the index, and its opposite face providedwith iine teeth, and a gear-wheel having the periphery thereof inclinedand meshing with the teeth of the slide to actuate the latter,substantially as described.

5. The combination of a base-plate having thetransverse openings,anindex having openings at its ends which align with the openings of thebase-plate, the screws passing through the aligned openings oi" thebase-plate and index to secure the same to the watch-movement, a slideguided by the index and having a groove or recess in which one end ofthe regulator is iitted, and a gear-wheel carried by the base-plate foractuating the slide, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
